目的 观察先天性骨性鼻泪管发育异常儿童骨性鼻泪管解剖的影像学特征.方法 回顾性系列病例研究.收集2009年1月至2013年6月在北京儿童医院眼科就诊的18例单侧先天性骨性鼻泪管发育异常患儿的CT检查资料,分析其异常发育的骨性鼻泪管解剖特征并测量双侧骨性鼻泪管高度,起始段骨性鼻泪管的横径及垂直径.单侧先天性骨性鼻泪管发育异常患儿双侧起始段骨性鼻泪管横径、垂直径进行配对t检验.同时将其双侧骨性鼻泪管高度进行配对t检验.结果 CT显示先天性骨性鼻泪管发育异常的典型解剖特征为骨性鼻泪管起始段未见明显异常,到达中段和末段骨性鼻泪管时,其出现明显的狭窄甚至闭锁.18例单侧先天性骨性鼻泪管发育异常儿童其患侧起始段骨性鼻泪管横径[(4.72±0.79)mm]均较健侧[(3.42 ±0.67) mm]明显扩大(t=5.665,P=0.000).18例单侧先天性骨性鼻泪管发育异常儿童其患侧起始段骨性鼻泪管垂直径[(5.45±1.07)mm]均较健侧[(4.35±1.01)mm]明显扩大(t=6.610,P=0.000).且健侧骨性鼻泪管高度明显大于患侧(t=5.931;P=0.000).结论 先天性骨性鼻泪管发育异常患儿其骨性鼻泪管闭锁的位置通常位于末段.正是由于骨性阻塞造成的泪道内高压力导致了患侧骨性鼻泪管起始段的扩大.

Objective To explore the radiographic characteristics of nasolacrimal canals in congenital nasolacrimal canal agenesis.Methods Retrospective case series study.The images of Computed Tomography of 18 children with unilateral congenital nasolacrimal canal agenesis who were treated in Beijing Children's Hospital from January 2009 to June 2013 were studied.The common features of abnormal lacrimal canals were analyzed.The heights of bilateral lacrimal canals,anterioposterior and transverse diameters at the original level of lacrimal canal were measured.The traverse diameters,anteroposterior diameters,heights of bony nasolacrimal duct between affected side and normal side were compared using paired t tests.Results The initial segment of abnormal nasolacrimal canal showed no obvious abnormalities,but it became significant stenosis or even atresia at the middle and terminal segments.The transverse (4.72 ± 0.79) mm and anterioposterior diameters (5.45 ± 1.07) mm of affected sides were larger than the values of normal sides (3.42 ±0.67) mm,(4.35 ± 1.01) mm at the original level of nasolacrimal canal with statistically significance (t =5.665,P =0.000 ; t =6.610,P =0.000).However,the height of nasolacrimal canal of normal sides were larger than the affected sides (t =5.931,P =0.000).Conclusions Atresia position of congenital nasolacrimal canal agenesis always located in the terminal segment.High pressure in the nasolacrimal duct caused by bony obstruction leaded to the enlargement of nasolacrimal canal in affected side.(Chin J Ophthalmol,2014,50:911-914)
